At the end of the Grand Archives, they came upon a massive stone wall blackened with flame. Ven'thur touched his skeletal hand to the charred rock, and as he did so, the indentations in the wall became highly visible, lined as they were with glowing purple energy.
The indentations formed into a circular pattern, and within that circle, there were further inscriptions that read out labels such as 'Main Hall', 'Residential Quarters', 'Alchemical Laboratory', 'Crystallography Center', 'Wandmaker', 'Scrollbearer', and so on, indicating a plethora of areas present all throughout the citadel.
"Hm, let me see here," said Ven'thur as he rotated his hand. With that movement, certain labels glowed brighter than others, indicating they were being selected.
